Windows 10 cannot be restored

Some files in system32 folder are incorrect. This caused Windows 10 not to boot correctly, and it went to the recovery environment.

System Restore failed! Reset this PC with Keep my files failed! There's no Internet or SD card support. I don't have a flash drive or a Windows installation disc, or another PC, or a writable optical storage. Please help!

System Restore fail code is 0x80070057. Any ideas why that fail code happened?!
